Solved Examples for an algorithm

1. Write an algorithm to assign the value of a variable to another variable.

The algorithm can be written as:

1. Declare X and Y.

2. Read value for X.

3. Assign value of X and Y.

4. Print value of X and Y.

2. Write an algorithm that prints the smaller of any two given numbers.

Solution:

Steps : 1. Read two numbers X and Y.

           2. Compare X and Y.

           3. If X is smaller than Y print X else print Y
